SPECIFICATION forming part of Letters Patent No. 230,478, dated July 27,1880.

Application filed J annary 10, 1880.

To all whom it may concern Be it known that I, IRA L. GRINNELL, of AnnArbor, in the county of Washtenaw, Michigan, have invented anImprovement in Sewing-Machine Attachments, of which the following is aspecification.

This invention relates to new and useful improvements in theconstruction of a supplementary foot for sewing-machines by means ofwhich hemmers, tuckers, and other attachments may be secured in placeand operated with exactness.

The invention consists in the peculiar construction and combination ofparts, as more fully hereinafter described and claimed. In the drawings,Figure 1 is a perspective of my device carrying a hemmer and detachablyattached to the presser-foot of a sewing-machine. Fig.2 is a perspectiveof the device detached and without the hemmer.

In the accompanying drawings, which form a part of this specification, Arepresents the body of my supplementary foot, made to conform in itscurvature to the curvature of the bottom of the presser-foot B and ofthe same width. It is provided upon one side with one or more flanges,a, and upon the opposite side with a wing-guide, b, and with aneedle-hole, c, which should be coincident with the slot ,in thepresserfoot through which the needle passes.

The body A is bent over upon itself, as at d, to hook upon the frontedge of the presserfoot, and is curved, as shown at e, at the oppositeend to rest against the heel of the presser-i'oot, where it is securedin place by the wire loop 0, one end of which passes through thepresser-bar D and is secured by the setscrew h.

The wing-guide is provided with a slot, i, 40 through which athumb-screw, 70, passes to secure the hemmer E or other device, intowhich a hole is tapped for the purpose.

What I claim as my invention is- 4 1. In combination with thepresser-foot of a 5 sewing-machine, a supplementary foot formed of aplate having two parallel upturned sides, one end bent at the toe toembrace the toe of the presser-foot and the other end turned up behindthe heel of the presser-foot to prevent said supplementary foot fromslipping off in any direction when the presser -foot is down,substantially as described.

2. The combination, with the presser-foot of a sewing machine and thedevice carrying 5 said foot, said device being provided with a hole, ofa supplementary foot having one of its ends turned up behind the heel ofthe presserfoot, a wire loop for holding said supplementary foot inplace, and a set-screw for secur- 6o ing said loop, substantially asshown and described.

3. A supplementary foot adapted to be attached to the presser-foot of asewing-machine, havingthe wing or guide b,provided with the slot i,substantially as described.

In testimony whereof I hereunto set my hand in the presence of twowitnesses.
